As per the summary, Funtoo Linux currently does not support this card. An update to the linux-firmware ebuild is required for reliable support of this hardware. See FL-7412 for the specific hardware that this is being validated on.

Another issue related to AX200 support – this hardware is simply not recognized by debian-sources-lts. Which shows me that debian-sources-lts is getting way too out-of-date and that Debian is not back-porting new hardware support to the kernel in a significant way. This means that we may want to switch to debian-sources, not debian-sources-lts, as our default kernel, as this kernel does support AX-200 and likely quite a bit of newer hardware.
